App/Window Switching Similar to MacOS

[GRMrGecko]

Hello,

I am opening this issue here as research shows a request for this feature pop-os/cosmic-epoch#490 which was told for organization reasons to open a request under cosmic-launcher. I tried searching it see if someone already opened an issue here regarding it, but did not see anything.

I'd like to see the option of adding:

1. A short cut to just switch between windows of the same application. In MacOS, this is Alt+` and for reverse order is Alt+~.
2. The ability to limit the default task switcher to one window per application. MacOS does this, and I for one prefer this option as to having many windows opened in one app floods the task switching.

Other platforms that offer these options include KDE Plasma, and I believe Gnome.
